Abstract: 11,494. Jetley, V. July 28. Refuse, collecting; scraping machines; sweeping - machines; elevating sweepings into carts and other receptacles; ; watering roads; snow - melting.-Relates to a road-scavengering machine which is also adapted to water roads and melt snow as it is collected, and is propelled and operated by a steam, gas, oil, or other hydrocarbon motor. The body of the machine is divided into two parts a and b ; the forward portion a, serving as a water tank, is connected by an india-rubber &c. tube with a perforated watering - pipe w. The rear part b receives rubbish &c., and contains a loose box which can be moved out at the side of the car by a screw operated by a handle. The box may slide or have rollers running on rails, which may have pivoted &c extensions supported on hinged legs to allow the box to be moved out sufficiently to dump its contents. The box has a sliding bottom engaging guides at the side and locked by a bolt catch &c. When the box is outside and the catch is released, the bottom may be withdrawn by the operating-screw. If the rubbish shoot is some distance away, the box is dumped into a car, which may be driven by a motor. The rail extensions may rest on this car, which may have hinged covers, an end fall-down door, and a screw-operated scraper to push the rubbish out. Three pilot brushes y of different sizes are arranged at each side near the front of the machine, or one brush of varying or uniform diameter may be used. These brushes are driven from the motor shaft z through belt, toothed, and bevel gearing, and are moved to and from the road by a hand-wheel 7, worms 8, and screws 9. Shovels with metal brush edges or scrapers 10, which may be alternated or replaced by picks 11, are mounted on an endless band br chain 12 and operated so as to feed the refuse &c. into the path of brushes 22 constructed like scoops and mounted on a wheel 21. These brushes sweep the refuse up an apron 23, at the top of which it is cleared by a spring wiper 24 on to an endless travelling band 25 leading to troughs 26 carried by endless chains 27 passing over wheels 28, 29, and 31, and guided in a framework 30. The feeder shafts 15 are attached to frames 17 on pivoted levers 18, which carry the sweeper shaft 20 and are adjusted by screws. A fixed sliding brush 32, attached to the levers 18, sweeps-up any rubbish left by the sweepers 22. Fig. 1 shows the snow-melting apparatus in position for use, it being moved forward when not in use. Petroleum burners 33 are surmounted by wire network 34 supporting coke &c. over which is arranged an endless band 35 of metal plates. As the top side of the band is cooled the bottom side is brought into its place, and so on. Continuously-moving shovels or scrapers 38, mounted in endless chains or bands 39 running over pulleys 40, pass over the upper plates 35, on to which the snow is discharged. A fixed hotplate 41 and a similarly-heated cistern 42 are provided. The chambers a and b may be connected by a pipe with a valve.
